11 Claims.

This invention relates to waste and overflow fittings such as areparticularly adapted for use on bath tubs and the like. It is customaryin making fittings of this type to employ a T mem- 1 her to which theoverflow, waste and outlet pipes are connected. In this construction theoverflow and outlet pipes are connected to oppositely disposed portionsof the T member and are consequently maintained in vertical alignment.Because of the variations in the slope or inclination of the sidewalls-of different fittings, the'waste pipe connecting the waste outletof the tub and the T member varies in length. This requires the use of aspecially formed waste pipe connection, depending on the slope of theparticular tub, and entails considerable difficulty in making thefitting.

The primary object of my invention, therefore, is the provision of acombined fitting whereby 20. the use of a T member is obviated and towhich the various connections are adapted to be made regardless ofthe'slope of the sides of the tub.

In carrying out the invention I prefer to combine the waste pipe L,overflow L connection and. discharge outlet connection into a singleintegral unit as will be hereinafter more particularly described.

A further object is to provide a fitting which is directly associatedwith the waste outlet and which may be utilized regardless of the pitchof the tub.

Another object is to provide a fitting which permits flexibility inassembling the various parts which are adapted to be connected thereon.

A further object is to provide an overflow L fitting or attachment whichis adjustable and which is maintained against the side walls of the tubat any desired angle. The overflow pipe extending therefrom is readilyconnected to the combined fitting regardless of the pitch or slope ofthe tub.

Another object is the provision of a waste plug strainer in which thewater outlet therethrough is considerably enlarged thereby permitting amore speedy emptying of the waste matter in the tub.

Another object is to provide a fitting of this type with one or moreadjustable connections of novel construction which are associated withthe said combined unit as will be hereinafter more particularlydescribed.

My invention further includes other objects, advantages and novelfeatures of design, construction and arrangement hereinafter moreparticularly referred to and which will be apparent from theaccompanying drawings.

Referring to the drawings, and particularly to Figures 1 and 2, theapparatus made in accordance with my invention includes a combinedfitting for the discharge of waste fluid either directly from the wasteoutlet of the tub or indirectly from the overflow connection associatedtherewith. This combined fitting is indicated at 20 and integrallyincludes a waste L connection 21 directly associated with the wasteoutlet of the tub, an overflow L connection 22 and a dis charge outlet23. 7

While the invention as hereinafter described will be made to relate toplumbing for the release of waste water, it will be understood that theflow of other liquids may also be controlled by the use of a fittingmade in accordance therewith.

The bath tub, or similar fixture, with which the invention is associatedcomprises a sloping side wall and a bottom wall as indicated at 24 and25 respectively. The bottom wall 25 of the tub has the usual wasteopening indicated at 26 in which a waste plug member 27 illustrated inFigs. 4 and 5 is located. The upper portion of the member 27 is flangedas indicated at 28 to maintain the same in a fixed position in theopening 26 substantially coincident with the bottom portion of the tub.The lower portion of the member 27 is threaded as indicated at 29 toengage a tapped opening 30 in the waste L portion of the fitting 20. Asuitable washer 31 is interposed between the under surface of the tuband the waste L connection 21 of the fitting to insure a water tightjoint between these respective members.

Cross bars 32 and 33 are integrally associated with the lower portion ofthe member 2'? to form a strainer therefor. The cross bars are arrangedsubstantially at right angles to one another and extend from the member27 in the form of a basket. This construction increases the areaavailable for the discharge of the waste water and consequentlyfacilitates a speedier emptying of the contents of the tub.

A circular rib 34 extends from the body portion of the fitting 20 and isinternally threaded as indicated at 35 to receive an externally threadedfastening member or nut 36. The portion of the casing 20 defining thedischarge opening 23 is curved in a downwardly direction as indicated at37, the lower surface of the same presenting a circular concave surfaceor seat 38 against which the curved upper portion of a discharge pipe 39is adapted to position. A gland ring member is indicated at 46, thepurpose of which will be hereinafter more particularly described.

In making this connection the upper portion of the discharge pipe 39 ismanually worked into a flange, the pipe being of lead or similar ductilematerial to approximate the concave surface 38 of the member 20. On thetightening of the nut 36 the upper surface of the gland ring pressesagainst the under surface of the pipe flange and forces the same toposition against the concave surface 38 as clearly indicated at 41. Dueto the flexible characteristics of the lead pipe, a firm fitting of thesame in the member 20 is assured in this manner even in the event thatthe cooperating members are not perfectly aligned.

The overflow L of the combined fitting 26 is inclined at an angleslightly more than 90 with the center line of the fitting 20. Thispermits a greater degree of flexibility in joining the overfiow pipe 42to the L portion 22 as will be hereinafter more particularly described.The upper portion of this fitting is screw threaded as indicated at 43to receive an internally tapped nut 44. The interior walls are bevelledas indicated at 45 to seat a washer 46 between its surface and theexterior of the overflow pipe 42. The Washer is preferably of lead orsimilar ductile material so that the inner surface of the tapped nut 44will force the washer to a tight fit against the bevelled surface of thefitting 20'when the nut is tightened.

In this construction the end of the overflow pipe 42 extending into thefitting 20 is not rigidly maintained in alignment with the overflow L.portion of the fitting. Regardless of the angle, which the pipe 42 mayassume in the fitting 26, a tight connection is assured through thewasher 46. A greater degree of flexibility is therefore obtained betweenthese respective parts by having the overflow L connection of thefitting 20 pitched'substantially at a corresponding angle to the averageslope or inclination of the side walls of a tub.

An overflow elbow connection 47 is threaded as indicated at 48 tomaintain the tapped end of the overflow pipe 42 therein adjacent thetub. The elbow connection 4'? comprises a bell shaped flange 49, thesurface of which is adapted to engage a washer or gasket 50. In theinterior of the elbow 47 are oppositely disposed recessed lugs, one ofwhich is indicated at 51, the inner surfaces of the same being adaptedto coact with the curved end surfaces of a cross bar 52, clearlyillustrated in Figure 1. A flanged ferrule 53 is adapted to extendthrough the overflow outlet opening in the tub wall to maintain thewasher 5O thereon. Bosses 54 and 54 extend from the ferrule and containscrew openings therein through which the screws 55 and 56 are placed toengage tapped openings 5'? and 58 in the cross bar 52 illustrated inFigures 3, 6 and '7. When the retaining screws 55 and 56 are drawn tightthe elbow 47 is firmly pressed against the washer 50 and connected tothe tub wall, regardless of its pitch, the curved surface of the crossbar 52 adapting itself to position against the lugs to accommodatevariations in the slope of the tub walls. The overflow opening iscovered by the usual plate or escutcheon 59 secured in position by acenter screw 60 in the tapped opening 61 of the cross bar 52. Thecustomary chain and stopper associated with the tub fixture are indicated at 62 and 63 respectively.

Referring to Figures 8 and 9, modified forms of the cross bar andoverflow plate are illustrated. The plate or guide for the overflowopening is constructed to include a circular recessed groove 64 adaptedto coact with the outer surface of the ferrule 53. The cross bar has asingle centrally tapped opening 65 for the reception of the screw 60. Inthis construction the elbow is secured to the tub by the use of a singlecentral screw from the plate to the cross bar, the ferrule beingmaintained in position against the plate and the washer against the bellshaped flange of the elbow. The cross bar adjusts itself within theoppositely disposed lugs in the elbow so that these respective membersare fastened together withoutexerting any bending action on the screw.The connection of the various members associated with the elbow iseasily facilitated regardless of the pitch or slope of the tub.

Referring to Figure 10 a modification of the combined fitting isillustrated in relation to the waste outlet of the tub. The combinedfitting unit is indicated at 66 and is directly associated with thewaste plug member 67 substantiallyas hereinbefore described. Theoverflow L connection integral therewith is indicated at 68 into whichan overflow pipe 69 extends and is adjustably maintained by a nut '70and washer 71. A discharge connection of the fitting is indicated at 72which in this instance is located in alignment with the overflow Lconnection, it being particularly desired to emphasize that the positionof the discharge outlet may be located at any desired point in thecombined fitting without departing from the nature and spirit of theinven- 1' tion. A discharge pipe is indicated at 73 and is adjustablysecured to the connection 72 by means of a nut 74 and washer '15.

Referring to Figures 11 and 12, the fitting is illustrated having adischarge connection located 1 at one side of the same as indicated at76. Waste outlet and overflow L connections are indicated at 7'7 and 78respectively.

The discharge connection 76 is internally threaded as indicated at 79 toreceive a tapped spud insert having a circular concave face 81 extendingoutwardly therefrom, the upper portion'being. substantially flush withthe end of the discharge connection 76. This connection is alsoexteriorly threaded as'indicated at 82 to receive an internally tappedfastening member or nut 83. A gland ring is indicated at 84. In a mannersubstantially similar. to that hereinbefore described, the upper portionof a discharge pipe 85,-which is of ductile or soft material such aslead, is manually worked into a flange approximating the concave surfaceof the spud insert 80. When the fastening member 83 is tightened on theoutlet connection 76, the gland ring presses against the under surfaceof the flanged pipe 85 and forces the same to position against theconcave surface 81 of the spud insert. The pliable character of the leadpipe insures that a tight fit be made around the entire periphery of thespud insert even in the event that the outlet connection 76 anddischarge pipe 85 are not in perfect alignment.

The inventive concepts herein disclosed may be employed in other desiredforms. Therefore, various modifications of the present improvements mayoccur to those skilled in the art and may be made without departing fromthe scope and purview of the invention.
